IMPROVEMENT IN HOT-AIR REGISTERS.

The Schedule referred to in these Lettera'Patent and making part of thesame Nature and Objects of the Invention.

My improvements consist in a new method of construction for operatingthe slats of a hot-air register or ventilator, and in a new constructionof the box which forms the body of such register, so that the end of thehot-air pipe which forms connection with the register can be leftcylindrical, instead of box-fashion, as is done at present.

Description of the Accompanying Drawings.

Figure 1 is a plan view of the top of the complete register,

Figure '2 is a sectional elevation, the section being a cross-sectionmade in the center of the length of the register.

Figure 3 is a plan view of one end of the register, the top orface-plate being removed, showing the 0peratingmechanism.

Figure 4 is a longitudinol sectional elevation.

Like letters indicate like parts in all the figures.

General Description.

in one piece, the cylindrical connection-piece e, upon which is to heslipped the cylindrical end of the hotair pipe, thus doing away with theordinary tin box end of the pipe, which is a radical improvement.

The slats s as s are hung on centers at each end, in the usual form.

At the end of the register, where is the operating mechanism, shortarms, .1: x x as, rise from the upper sides of the slats, a little oneside of the center, from the tops of which arms project wrist-pins,which play in slots in the sliding bar 0, which sliding bar iscontaiuedand slides in the end piece b.

These wrist-pins are partially seen in figs. 2, 3, and.

4, and are indicated by the letters n n n n.

The slots in m an m are partially seen in fig. 2.

The spring z, afiixed to the side of the sliding bar 0 and pressingagainst the inside of the frame 0, holds the slats at any desired pointof opening or closing.

The bar I, which isa part of the sliding bar 0, projects up through theslot y in the face-plate a, by means of which the slats can be opened orclosed at will by the hand or foot of a person.

It is obvious that, as the sliding bar 0 is moved back and forth,'itwill carry the wrist-pins n n n n, which are free to rise and fall inthe slots in m m in in the sliding bar Q, with it, and thus open orclosethe slats as desired.

It is customary to construct the parts of such registers of cast metal,preferably iron.

,. Claims.

- I- claim as my invention- The sliding bar 0, having the bur l on itsupper edge and the slots in in its lower edge, and made substantially asdescribed, for the purpose set forth.

Also, the sliding bar 0, in combination with the spring 2 and frame 0,the whole being constructed and Witnesses WM. E1). Snuosns, H. B.WEAVER.
